No.14/638,759, filed on Mar. 4, 2015, which is currently under allowance,which claims the benefit of U.S. Provisional Application No. 61/947,620,filed on Mar. 4, 2014, which the disclosures of which are herebyincorporated by reference in their entirety for all purposes.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to electronic controls and displays withina motor vehicle, and, more particularly, to electronic controls anddisplays on a steering wheel of a motor vehicle.

2. Description of the Related Art

Steering wheels typically have fixed buttons with permanent functionsand permanent types which the driver may or may not find useful. Thatis, current steering wheels provide fixed-function controls which areusually in the form of pushbuttons or scroll wheels which are notconfigurable by the user.

SUMMARY OF THE INVENTION

The invention may provide a steering wheel including one or moreback-lit liquid crystal diode (LCD) displays with touch screens. Thedisplays can display control widgets such as buttons, sliders, etc. aswell as display widgets with graphical or textual information such asthe selected radio station, volume level, etc. Due to the nature of theLCD/touch screen device, the controls or information widgets can beuser-configurable. The user can decide which types ofcontrol/information widgets are most useful and may configure theLCD/touch screen device(s) to include the most usefulcontrol/information widgets.

The present invention may provide user-configurable controls to ensurethat the driver has instant access to the controls/information hedesires. The invention may enable the driver to configure the controlsand display such that the driver has the controls/information of hischoosing conveniently located on the steering wheel. Thus, the driverdoes not need to take his hand off the steering wheel to adjust radioand/or environmental controls.

The invention may include one or more LCD/touch screen devices locatedon the steering wheel within close proximity to the driver's hands.There may also be an information display that is centrally located toprovide response/status/configuration messages or graphical data. Theinformation display may not include a touch screen or betouch-sensitive.

In one embodiment, the invention comprises an entertainment systemcontrol arrangement for a motor vehicle including a graphical liquidcrystal display with a configurable touch screen. The graphical liquidcrystal display is disposed on the steering wheel. A processor iscommunicatively coupled to the graphical liquid crystal display. Theprocessor prompts a user to select a function to assign to theconfigurable touch screen. The processor assigns the selected functionto the configurable touch screen.

In another embodiment, the invention comprises a method of providing anentertainment system control arrangement for a motor vehicle, includingproviding a steering wheel. A graphical display device with aconfigurable touch screen is provided. The graphical display device andtouch screen are disposed on the steering wheel. A processor iscommunicatively coupled to the graphical display device. A user isprompted a user to indicate acceptance or rejection of a proposedassignment of a function to a first portion of the configurable touchscreen. The user's indication is sensed. The indication includes theuser touching either a second portion of the configurable touch screento accept the proposed assignment or a third portion of the configurabletouch screen to reject the proposed assignment. The function is assignedto the first portion of the configurable touch screen only if the usertouching the second portion of the configurable touch screen has beensensed.

In yet another embodiment, the invention comprises a method of providingan entertainment system control arrangement for a motor vehicle,including providing a steering wheel. A graphical display device isprovided with a configurable touch screen. The graphical display deviceand touch screen are disposed on the steering wheel. A processor iscommunicatively coupled to the graphical display device. A user isprompted to indicate acceptance or rejection of a proposed assignment ofa first arrow to a first portion of the configurable touch screen and asecond arrow to a second portion of the configurable touch screen. Theuser's indication is sensed.

At least one embodiment of the present invention will be shown anddescribed, and this application may describe and/or show otherembodiments of the present invention. It is understood that anyreference to “the invention” is a reference to an embodiment of a familyof inventions, with no single embodiment including an apparatus orprocess that is necessarily included in all embodiments, unlessotherwise stated. Further, although advantages provided by someembodiments of the present invention may be described, it is to beunderstood that other embodiments may not include those same advantages,or may include different advantages. Any advantages described herein arenot to be construed as limiting to any of the claims.

FIG. 1 is a plan view of one embodiment of a steering wheelentertainment system control arrangement 10 of the present inventionwith configurable touch screen LCD controls. Steering wheelentertainment system control arrangement 10 includes a graphical LCDdisplay 12 which may not include a touch screen and may not betouch-sensitive, and graphical LCDs 14, 16 with touch-sensitive touchscreens. A microprocessor 34 may be communicatively coupled to each ofdisplay 12 and graphical LCDs 14, 16.

Graphical LCDs 14 and 16 each include a respective plurality of sectionsor portions which each have a respective function andfunction-identifying icon displayed thereon. In the embodiment shown,the portions or sections are square or rectangular. However, it iswithin the scope of the invention for these sections/portions to havedifferent, possibly irregular, shapes.

Assigned to one of the sections/portions is a configurable controlwidget 18, which may be a pushbutton that controls voice commands, forexample. That is, a user may press pushbutton 18 to cause the system toaccept voice commands. Graphical LCD 14 may also include configurablecontrol widgets in the form of left and right pushbutton controls 20, 22for a menu. That is, the user may use pushbuttons 20, 22 to move anon-screen cursor in left and right directions within an on-screen menu.Graphical LCD 14 may further include a configurable graphicalinformation widget 24, which may indicate sound levels, for example.Lastly, graphical LCD 14 may include a configurable control widgetpushbutton 26, which may be depressed to initiate or answer a phonecall, for example.

Graphical LCD 16 includes configurable control widgets in the form ofchannel up and channel down pushbutton controls 28, 30. That is, theuser may use pushbuttons 28, 30 to change channels or stations in onesequential direction or the opposite sequential direction. Graphical LCD16 may further include a configurable control widget slider 32, whichmay be used to control or change the audio volume level, for example.

During initialization of arrangement 10, microprocessor 34 may presentthe user with a menu of configuration choices on LCD display 12. Forexample, display 12 may query the user regarding which functions hewould like to assign to each of widgets 18, 20, 22, 24, 26, 28, 30 and32. In one embodiment, the configuration process may begin with the userbeing asked whether he would like to assign left and right arrows tocontrols 20, 22 and/or assign up and down arrows to controls 28, 30. Atleast one of the widgets may initially be designated a “yes” pushbutton,and another widget may initially he designated a “no” pushbutton. Theuser may use these “yes” and “no” pushbuttons to accept or reject theconfiguration choices presented on display 12, which may be defaultconfigurations. If the user does accept two or all four of these arrowassignments, then the user may subsequently use the arrows to navigatethrough a menu of other configuration choices presented on display 12for the remaining widgets 18, 24, 26 and 32.

In another embodiment, the user is audibly queried via an in-vehicleloudspeaker 36 as to which functions he would like to assign to each ofwidgets 18, 20, 22, 24, 26, 28, 30 and 32. Additionally, oralternatively, the user may provide his configuration choices orally,and these oral responses may be detected by an in-vehicle microphone 38.The loudspeaker 36 and microphone 38 are communicatively coupled toprocessor 34.
